IMPROVEMENT IN M EDICATED CORN-FILES.

Specification forming part of Letters Patent No. 156,] 73, dated October20, 1874; application filed April 28,1874.

To all whom it may concern:

Be it known that I, Mrs. MIRIAM P. H. PAT- TERSON, of Chicago, in thecounty of Cook and State of Illinois, have invented an Improvement inMedicated Corn-Files of which the following is a specification:

The nature of this improvement relates to the medication of a corn-filefor curing corns and other excrescences; and its object is to somedicate the file that the proper benefit will be derived from itwithout the use of plasters or other medioaments.

In the accompanying drawings the file is shown in perspective. It ismade from a piece of Wood, with a handle, A, and blade B. The blade isdipped into melted white glue; then immediately into fine sand mixedwith about one-sixteenth part of emery; then left to dry.

When dry, the blade is dipped into a compound made of the followingingredients Six grains of powdered camphor gum; ten grains of powderedalum; fifty grains of arsenic; one pound of best Vermilion paint, thewhole thoroughly mixed; or the medicated paint may be applied to thesanded portion of the tile by means of a brush, if preferred.

The file is ready for use when thoroughly dry, and should be used dryupon corns or other excrescences.

What I claim as new, and desire to secure by Letters Patent, is

The compound for medicating corn-files, made of powdered camphor-guin,powdered alum, and arsenic, in about the proportions and appliedsubstantially as herein set forth.
